core::Size const  glycosylation_residue,
core::Size const  donor_residue 
)

Calculate additional distance metrics for glycosylation.

For specific glycosylation cases when the sugar is donated from a UDP to a substrate This function will be updated as more cases are added for sugar donors For example, pdb_HWU is encountered in O-glycosylating enzymes GalNAcTs (20 enzymes) TODO: Create a dictionary of possible donors and how to treat them.

TODO: generalize

core::Real protocols::glycopeptide_docking::calculate_sampled_distance ( core::pose::Pose const &  pose,

)

Calculate distance between donor and substrate.

Tracks distance between donor and acceptor. If the distance exceeds a specified distance, the protocol terminates sampling early.

setup specialized foldtree.

The foldtree for glycosylation can be set up in two ways. The "outward" foldtree or the "docking" foldtree.
The docking foldtree is the standard docking foldtree and is setup across the enzyme-peptide or enzyme -glycopeptide interface.
The outward foldtree is anchored at an "anchor residue" specified with the anchor_residue flag. In the absence of this specification the residue_to_glycosylate is also the anchor residue. This foldtree goes outwards in all directions from the anchored position. The outward foldtree is especially useful for glycopeptide glycosylation i.e. glycosylating a pre-glycosylated peptide at a new site. In such a case, if the binding site of one sugar on the peptide is known, the preglycosylated site on the peptide substrate can be specified as the anchor residue. This allows for a floppy tail type of sampling. Another useful choice for anchor residue is the site of glycosylation, especially when the user is sampling with the site of glycosylation already glycosylated. In the current implementation, a specialized foldtree is setup for a pose. User-specified foldtree is not supported.
